💡 Hint

Common Mistakes

Trying to access 'token' directly from pm.response without parsing JSON.

Using incorrect property names like 'status' or 'headers'.

The pm.response.json() method parses the response body as JSON. To get the 'token' value, use pm.response.json().token.

Complete the code to check if the response status code is 200.

Postman

pm.test('Status code is 200', function () { pm.response.to.have.status([1]); });

Drag options to blanks, or click blank then click option'

D500

💡 Hint

Common Mistakes

Using 404 which means 'Not Found'.

Using 201 which means 'Created' but not the expected here.

The status code 200 means the request was successful. We check it using pm.response.to.have.status(200).

💡 Hint

Common Mistakes

Using parentheses like a function call.

Trying to access property without dot or brackets.

To access a property in a JavaScript object, use dot notation without parentheses: .userId.

4fill in blank

Fill both blanks to extract the 'email' from the first user in the 'users' array in the response.

Postman

let email = pm.response.json().[1][[2]].email;

Drag options to blanks, or click blank then click option'

C1

Ddata

💡 Hint

Common Mistakes

Using 'data' instead of 'users' as the array name.

Using index 1 which is the second user.

The response has a 'users' array. To get the first user's email, access users[0].email.

5fill in blank

hard

Fill all three blanks to create a test that checks if the response JSON has a 'success' property set to true.

Postman

pm.test('Response has success true', function () { pm.expect(pm.response.json().[1]).to.eql([2]); pm.expect(typeof pm.response.json().[3]).to.equal('boolean'); });

Drag options to blanks, or click blank then click option'

Asuccess

Btrue

Dstatus

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'status' instead of 'success' property.

Using string 'true' instead of boolean true.

We check the 'success' property equals true and that its type is boolean. Both blanks 1 and 3 refer to 'success'.
